Slow boot

Yes i know this has been brought up before but... When i had my 16 gig ipot jailbroken with a bunch of apps it was slow at booting up so i decided to restore it with 1.1.2 and with 1.1.3 and it is still slow at booting up. It takes about 5 to 6 secs longer than a un jailbroken ipot turning them on at the same time. I have restored my ipt A LOT! Could this be the problem?? or it could it be from jailbreaking it a bunch of times??
